JavaScript 时间戳操作：

//第一种方法
var timestamp = Date.parse(new Date());
结果：1280977330000

//第二种方法
var timestamp = (new Date()).valueOf();
结果：1280977330748

//第三种方法
var timestamp=new Date().getTime()；
结果：1280977330748

//第一种：获取的时间戳是把毫秒改成000显示，

//第二种和第三种是获取了当前毫秒的时间戳。

var toTime = (function(){
//JavaScript函数：
var minute = 1000 * 60;
var hour = minute * 60;
var day = hour * 24;
var halfamonth = day * 15;
var month = day * 30;

function getDateDiff(dateTimeStamp){
var dateTimeStamp = dateTimeStamp*1000;
var now = new Date().getTime();
var diffValue = now - dateTimeStamp;
if (diffValue < 0) {
//若日期不符则弹出窗口告之
//alert("结束日期不能小于开始日期！");
}
